Blue Nankeen Exhibition Hall’s name is a bit misleading. There’s a display upstairs explaining how nankeen cloth is starched and hand-dyed a rich shade of indigo, but this is primarily a place to pick up beautiful textiles, clothing, and accessories. Nankeen, also known as blue calico, originates from Nanjing, China’s onetime capital (nanjing means “southern capital”). You’ll find it used here in mandarin-collar shirts for both men and women, pint-size tea dresses for little girls, soft-soled slip-on shoes, hats, and bags. If you’re handy with a sewing machine, you can even buy fabric by the meter. No discounts.
